Specification of Letters Patent.

Patented March 16, 1909.

appiimion ma my va1, mos.l smal Na. 434,012.

To all whomit may. concern:

Be it known that 1I, JEssE L. HrTz, a citi- Azen of the United States'ofAmerica, residing at Chicago, in the county of Cook and State ofIllinols, have invented certain new and useful Improvements inTooth-Brushes, of which the following is a specification.

This invention relates to improvements in tooth brushes and its objectis to provide means whereby a quantity .of toothpaste or othersemi-solid dentifrice maybe contained Within the handle of the brush,and a small uantity thereof forced into the bristles of t e brush,whenever it is desired to use the same.

Another object is to provide means whereby the ordinary commercial softmetal tube, such as is frequently used to contain tooth paste, may besecured in the handle and a quantity of the paste fed into the bristles.

Another object is to simplify and cheapen devices of this kind and tootherwise improve uponl the construction thereof.

Tosuch end this invention consists in certain novel features ofconstruction and arrangement, a description of which will be found 4inthe following specification and the essential features of whichlwillbemore definitely pointed out in the claims appended hereto.

The invention is clearly illustrated in the drawings furnished herewith,in which- Figure 1 is a side view of the preferred l form of my brush.Fig. 2 is a central, vertical,.longitudinal section thereof, showing theparts in-the position occupied when the outlet or discharge port isopened to discharge a quantity ofthe paste. Fig. 3 is an end view of thehandle and *tube .contained therein. Fig. 4 is a vertical cross sectiontaken on the line4-4 of Fig. 1 and Fi 5 is a view artly, -1n sideelevation and art y in vertical, ongitudinal section of a s ightly'modified form of construction.

Referring to these drawings, A, represents' the head of the brush, andB, the handle. The head comprises the usual back 1 1, having thebristles 12, upon its lower face and said back is provided withacentral, longitudinal bore 13, which is adapted to receive the neck 14,of the handle B. Said neck is longitudinally movable the bore and formsa assageway which opens out through an outet or discharge port 15,formed at the end of the bore 13;

I desire to provide some simple means for preventing accidentallongitudinal movement of the parts when the outlet port is closed-by theneck 14, and as shown this consists in a small knob 16, which may beformed by indenting the wall of the back 11, and said knob is adaptedto'enter and seat itself in a de ression 17, formed-in the neck 14. Itis evldent that when this knob is seated in the depression some littleforce must be exerted to move the back u on the neck. I have providedmeans for eepin the outlet port `15, clear, and as shown, this meansconsists in a cleaning pin 18, which is secured in the neck 14, andadapted to move back and forth across the opening 15, whenever the back11, is moved upon the neck 14. It is evident that this opening may beclosed by ushing theV back 11, toward the handle unti the end of theneck covers the opening 15, and engages with the end wall 19, of thebore 13, and that by reason of the engagement of the knob 116, with thedepression 17, the neck 14, will be securely held in lace over theopening 15.

I-prefer to ma e the handle in the form of a flattened or oval shapedtube, as seen in Fig. 3, and this handle is adapted to receive a tube20, such as is usually employed to contain the tooth paste. The neck 21,of the tube 20, is threaded, and upon said threaded neck is ordinarilyscrewed a cap (not shown). i This cap is first unscrewed and the tubescrewed into an internally threaded portion 24, of the neck 14.Communication is thus established between the interior of the tube andtheyoutlet opening 15, and it is evident that by reducing the size ofthetube 20, the contents thereof may be forced out through the outletopening 15. I provide a key 22, upon the end of the tube whichkeyprojects out through a slot 23, formed in the wall of the handle whereit may be conveniently grasped by the user to wind up the tube. Bwinding up the tube the size thereof is decreased and the contentsforced out through the neck 14, and-opening 15, and in between thebristles of the brush. When the tube is empty it may be removed byfirst. unwinding the same until the key is brought beyond the end of thehandle, whereupon the tube may be unscrewed from the internal threads inthe neck 14, and a filled tube screwed into place -to take the place ofthe empty one.

In operation the back 11, is pulled forward to uncover the` dischargeopening 15, after which the key is given a slight turn, thus forcing aquantity of the tooth paste out' through the opening 15. The back 11, isthen pushed back, closing the opening 15, after which the brush may beused in the ordinary manner. 'lhis forms an exceedingly simple andconvenient device and one which is not liable to get out of order.Furthermore, Whenever it is desired to clean out the brush the tube 20,may be unscrewed and water allowed to run through the handle and bore13. v

In the construction shown in Fig. 5, the neck 14a, is revolubly mountedin the back 11, of the brush and the end of said neck is cut oil' on anangle as shown at 141. This provides an overhanging end which will coverthe opening 15,wl1en the parts are in one position or the handle may beturned half way around so that the opening will be uncovered. I preferto employ devices for properly positioning the back of the brush withrespect to the neck, and as shown, have provided a knob 16a, .upon theneck which is adapted to engage with depressions 17,

formed in the bore of the back. This contrivance is arranged to hold theback in a position whereby the outlet opening will be either covered oruncovered by the end of the neck 14a.

More or less variations of theparts are possible without departing fromthe spirit of my invention, and I desire therefore not to limit myselfto the exact construction shown and described.

I claim as new and desire to secure by Letters Patent:
